T0 (oZZ whom it may concern: 1

Be it known that 1, CHARLES J. HAGGSTROM, a citizen of the United States, residing at Warren, in the county of Warren and State of Pennsylvania, haveinvented certain new and useful Improvements in Vises; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention is an improved vise adapted for use both by m'etahworkers and woodworkers; and it consists in the peculiar construction and combination of devices hereinafter described and claimed.

The object of my invention is to provide a simple, cheap, and compact vise which is adapted to be used on a bench or other suitable support and to be disposed in any desired position.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a vise embodying myimprovements. Fig. 2 is atop plan view of the same. Fig. 3 is a detail horizontal section taken on the plane indicated by the line a a of Fig. 1. y

In the embodiment of my invention here shown I provide the body portion 1 of the vise with a fixed jaw 2 and at the end opposite the said jaw with a projecting trunnion 3, which is cylindrical in shape. On opposite sides of the body portion are projecting trunnions 4 5. All the trunnions are of the same diameter and shape, so that either of them may be placed in a clamp-ring 6. The body portion is provided with a guide-opening 7, which extends from one side to the other, and is also provided with an opening 8 at right angles to the said guide-opening, in which opening 8 is inserted a block 9, theinner end of which projects into the opening 7 and is provided with a threaded transverse opening 10, whereby the said block is adapted to serve the purposes of a nut. The movable jaw 11 is carried at the outer end of a slide-bar 12, which extends through and is adapted to travel in the guideopening 7. The said slide-bar has a longitudinal slot open at its lower side, which slot 13 clears the upper end of the block 8, forming the nut. Extending longitudinally through the slide-arm is an adjusting-screw 14, the

threads of which engage the threaded bore of the nut-block, and the end portions of the said screw are swiveled in the ends of the said slide-bar, the latter having bearing for the unthreaded end portions of the screw and a swiveled ring or flange 15 being secured on the said screw near one end thereof and coacting with the enlarged head 16 of the screw to prevent endwise movement of the said screw in the said slide-bar. ing the screw 14 the slide-bar may be moved to move the jaw 11 toward or from the fixed jaw 2 to clamp the work between them. A bar 17 of usual form is shown as adapted to slide longitudinally in an opening with which the head 16 of the adjusting-screw is provided.

The clamp-ring 6 is adapted to be placed on the top or on one side of a bench (indicated at a) or any other suitable support.

Said clamp-ring has an open ring provided with outstanding base-lugs 18, which are adapted to be secured by means of bolts or other suitable devices 19 to the bench, and the said split clamp-ring is further provided with a pair of outstanding lugs 20." One of the said lugs 20 has a smooth opening and the other is provided with a screw-threaded opening. A clamping-screw 21 operates in the said openings and is adapted to clamp the clamp'ring on either of the trunnions with which the body portion of the vise is provided to secure the vise in any desired position, according to the nature of the work,

and said adjusting-screw 21 is provided at its outer end with a pivoted lever-handle 22, by means of which it may be readily turned. The said lever-handle is of such weight that it serves to prevent casual rotation of and hence to retain the said screw in place when the clamp-ring is appropriately adjusted.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention,

Hence by turnwhat I claim as new, and desire to secure by Letters Patent, is

1. A Vise comprising a body portion having a fixed jaw, a plurality of angularly-disposed trunnions, and a guide opening, in combination with a slidebar adapted to travel in said opening and having a movable jaw, a fixed nut in the guide-opening, a clampingscrew carried by said fixed nut and having a swiveled connection with the slide-bar, and a supporting element adapted to engage either of the trunnions to secure the vise in any desired position, substantially as described.

2. A supporting element comprising a split clamping-ring having means whereby it may be secured on a support, and further provided with a set-screw, in combination with a vise having a body portion provided with a fixed jaw and a plurality of angularly-disposed trunnions adapted to be engaged by CHARLES J. HAGGSTROM.
